9 fixes for Windows 10 won’t wake up from sleep
When Windows 10 won’t wake up from sleep, the problem might be the power plan on your computer. This may be because of an error with the power settings. You may need to update your power-saving settings to resolve this issue. Here’s how:
Fix 1: Use an override power plan
When you need to use some peripherals like USB flash drives or binding docking stations that draw more than 500 mA and don’t support USB selective suspend (you can check in device manager if your devices support it), then working with a power plan like High performance can be a problem if you are using it in battery mode. That’s because when set to high performance, USB selective suspend is disabled by default. And that means the peripherals won’t work properly when you are on battery power.
You can however override this behavior by creating your power plan that has the same settings as high-performance but with USB selective suspend enabled for both battery and plugged in operation. Here’s how to do it:
From the Start menu select Settings > System > Power & Sleep > Additional Power Settings
Click on Change plan settings next to the current power plan you are using. If you don’t see it, click on Show additional plans first.
Click Edit Plan Settings in the window that appears. (see screenshot) Select turn off hard disks (in case it isn’t already selected) and then click Change advanced power settings. In the window that appears go to Hard Disk,> Turn Off Hard Disk After. If it isn’t already set to 1 minute then change the setting by clicking on the up arrow or type in a new value.
Click OK and go back to the Power & sleep screen. Now click Change plan settings next to your current power plan again, followed by Change advanced power settings. Scroll down to Sleep > Allow Wake Timers and make sure this is also turned off (set to Disabled) or else Windows will prevent your computer from going into sleep mode. Click OK and save any changes you made so that they are applied to all power plans. You should now be able to wake your PC from sleep!
Fix 2: Make sure Windows 10 not waking up from sleep isn’t caused by specific devices
Unexpectedly failing to wake up after sleep sometimes means there’s something wrong with one or more of your connected devices but before assuming the worst, best to test all your connected devices, if they are working fine, then it’s safe to assume Windows 10 fall-asleep bug.
Use Device Manager to check all your connected peripherals are working fine, if not, have them checked by the manufacturer or a specialist to get them fixed/replaced. If they’re working, you can go ahead and jump straight in fixing Windows 10 sleep problems that won’t wake up from sleep.
Fix 3: Disable any wake timers – New Task Scheduler Method for Windows 10 PCs
If you’re on a laptop and don’t want to prevent your PC from going into Sleep mode altogether but just want to shut down those annoying power drains that prevent your computer from waking up after it goes into Sleep mode then this method is for you.
Wake timers are pretty complex for troubleshooting, so best if you get a computer technician involved in this step.
Fix 4: Make sure Windows 10 not waking up from sleep isn’t caused by scheduled power plans
Scheduled power plans usually trigger at a specific time and the best way to solve this is to simply remove them. This article explains how you can do that manually but if you don’t want to go through the hassle, here’s what you need to do:
1) Type “power options” in the search box and click Change plan settings next to your active power plan (highlighted in blue).
2) Click Change advanced power settings.
3) Scroll down and expand Wake timers and disable any wake timers set for longer than 1 minute (deleting them is often easier). You will likely have to disable multiple wake timers depending on the number of power plans you’re using.
4) Click Change settings that are currently unavailable and scroll down to Sleep. Expand Allow hybrid sleep, uncheck it and click Apply. This will allow Windows 10 to go into a complete hibernation state instead of simply pausing your system which can make it wake up from sleep almost instantaneously.
5) Check to Prevent the computer from sleeping automatically if it is plugged in and you should be good to go! Remove active scheduled tasks Another reason why your PC goes straight back to sleep could be a task set for a specific time. If there isn’t anything weird going on with your computer, these tasks shouldn’t trigger at all but either way, how can we know for sure? We’ll need to open up Task Scheduler app. Start by opening the Start menu and simply tapping on the Task Scheduler shortcut.
Expand Task Scheduler Library and navigate to Microsoft > Windows > Power-Troubleshooter. Once you’re here, select Disable All Power Troubleshooting and click Apply. This will disable all scheduled tasks automatically created by this tool so they don’t interfere with your current sleep settings.
Fix 5: Check for updates and patches
In addition to running System File Checker from elevated Command Prompt, you should also consider keeping your device up-to-date by checking for new updates at least once a month.
Fix 6: Check device connections
Some external devices (for example, a USB mouse) may have been disconnected from the computer. In such a case, make sure all your connected devices are reconnected to your Windows 10 machine.
Fix 7: Update device drivers
This problem might be caused due to an outdated driver for one of your devices. If you’re not sure what’s causing the problem, try updating your drivers and see if it helps. You can use the Device Manager to update drivers for individual devices or check online for updated versions from their official makers/vendors. Be sure to install only those updates which are required by the error you’re seeing on the screen right now–you don’t want to put any other programs at risk by installing random updates!
Note that if you have multiple GPUs installed in your machine (e.g., two different brands) it may be wise to avoid installing the latest driver in case there’s any kind of conflict between them.
After applying these updates and rebooting the system, you should see that this issue is resolved.
Fix 8: Disable fast startup
Your Windows 10 machine’s fast startup feature may be causing the system to not wake up from sleep when you start it again. If so, disabling this feature could fix things for you. So, go ahead and open Power Options by clicking on the battery icon in your taskbar which can be found at the bottom-right corner of your screen, and then choosing ‘Power & Sleep’ in its left pane. Then click on the “Choose what closing lid does” link and set it to ‘Do Nothing’. That should do it!
After disabling this feature and rebooting the PC, we hope things are back to normal now. Microsoft has explained why the machine is not waking up from sleep via a system event log entry that says, “The previous shutdown was unexpected.”
All of these fixes are designed for Windows 10 but they can work on older versions of Windows too. So if you’re using an older version of the OS, don’t worry! We hope this helps you solve your problem and get your computer waking up without any issues.
Fix 9: Update your BIOS
Try updating your BIOS if you haven’t done so in a long time. BIOS updates often include bug fixes and other improvements that can resolve the cause of such mysterious issues. To get started, simply visit your computer or motherboard manufacturer’s website and download the latest version for your model.
